Method for mass production of carbon nanotubes by alkali metal catalyst and carbon nanotube synthesized from it

摘要

The present invention relates to a method for mass synthesis of carbon nanotubes using an alkali metal catalyst and to carbon nanotubes synthesized therefrom, and more particularly, without using a non-alkali metal catalyst such as iron, cobalt, nickel, and excluding hydrogen. It relates to the synthesis of pure carbon nanotubes using an alkali metal catalyst based on a group 1 element. The present invention comprises the steps of preparing a carbon source; Dissolving an alkali metal-based alkali metal-containing compound in a solvent to form an alkali metal catalyst precursor solution; By heat treatment while spraying the alkali metal catalyst precursor solution while supplying the carbon source, the alkali metal of the sprayed alkali metal catalyst precursor solution is aggregated into the nano catalyst, and the carbon source is dissolved and crystallized in the nano catalyst to grow carbon nanotubes. The nanocatalyst is evaporated while being removed; a method for mass synthesis of carbon nanotubes using an alkali metal catalyst, characterized in that it includes, and carbon nanotubes synthesized therefrom, as a technical point.
